I don’t know a thing about golf apart from that it’s very popular, so I won’t offer advice on which ebooks to buy. There are zillions of ebooks on the subject to choose from. However, some golf balls, socks, tees or a pair of golfing gloves would fill up a book bag for a golfer very nicely.

3. Fishing

Again, there are lots of books out there to choose from, but this looks interesting – Fishing – Learn from the Tips and Laugh at the Tales. Into the book bag go some hooks, flies, line, disgorger, lures, small bags of boilies etc – the list of little fishy gifts is endless.

You could pop an old-fashioned compass into the bookbag, but most useful for the geocaching man in your life would be a selection of small items he can put in the caches he finds. What happens in geocaching is that you take a small item from the cache you find after signing the log, and leave something in its place. You could also put in a plastic container with a very tight seal in case the geocacher wants to create his own one somewhere.
